Propensity to Patent, Competition and China’s Foreign Patenting Surge
What determines the decision of an inventor to seek patent protection in a foreign jurisdiction, particularly one where intellectual property rights protection is weak? This paper focuses on competition as a determinant of the patenting decision in the context of the recent foreign patenting surge in China. Using a database that comprises of all patents granted by China’s State Intellectual Pro...
متن کاملActive surge control of centrifugal compressors using drive torque
A novel aproach to active surge control is presented. A centrifugal compressor driven by an electrical motor is studied, and the drive itself is used for surge control, thus elliminating the need for additional actuators. It is shown that by using the rotational speed of the motor as control, previous unstable operating points to the left of the surge line can be made globally exponentially sta...
متن کاملActive surge control of compression system using drive torque
Novel control laws for a compression system using only the drive torque as control input are presented. Stabilization of any desired operating point is achieved with static or dynamic feedback. The stability results are derived using backstepping and passivity techniques. 2007 Published by Elsevier Ltd.
متن کاملDrive torque actuation in active surge control of centrifugal compressors
A novel aproach to active surge control is presented for a centrifugal compressor driven by an electrical motor. The main idea of the paper is to use the drive itself for surge control. This eliminates the need for additional actuators, and has the potential of energy efficient operation. It is shown that previous unstable operating points to the left of the surge line can be made globally expo...
متن کاملPatent Subject Matter under Chinese Law ?
In the Citibank-Patent-Case, the underlying issue is whether E-bank related business methods are subject matter of patent under Chinese law. At first flash, there are at least two barriers to patent protection for Citibank to cover. The first, E-bank related business methods only function with the help of computer software, so the coming issue is whether computer software is patent subject matt...
